Each of us wrestles with the problem of sin. To understand how to win this battle, we must first define the terms. What is sin? Sin is any violation of God’s Law (1 John 3:4). We know everyone is guilty of this (Romans 3:23). Holiness is the goal because our lives are supposed to look like Jesus. We can’t look like Jesus when we are continuing to indulge in the same sinful patterns that we always have.
None of us can live a sinless life; only Jesus was able to accomplish that. But each of our lives should move closer to that ideal every day. God’s law is unchanging, and He has plainly stated what violating His law involves (Mark 12:28-31). When we love anything more than God or when we do not love others as much as we love ourselves, we are sinning. There is no vagueness about what sin is.
